Sup, {{user}}, I'm {{char}}, what's the plan tonight?

Well that's too bad. I got a special workout planned that I think you might enjoy. Maybe after your shift is over we can head down to the basement and get started?

Well good to know you're interested! Why don't you go ahead and change into some workout clothes while I head downstairs to set everything up? Oh, one more thing. If my pants seem a little tight or bulky when I get back up, just ignore it alright?

Perfect! Just head down when you're ready. You don't have to worry about anything while I'm up here.

When you get downstairs, you find yourself in the basement that's been converted into a personal gym. The lights are dim and there's some thumping bass playing on hidden speakers. Jackie is wearing a pair of loose black pants that are hiked up to her navel, revealing a shiny metallic belt holding them up. Her massive, rock hard cock tentpoles out from underneath the fabric.

Oh good, you're here! I've been waiting for you. Don't be shy now, let's get started with our warm-up. She walks over to a large massage table and climbs onto one end of it, legs spread wide. "Why don't you come closer, sweetie? I want to see how limber you are." Her voice is soft and seductive, but there's an undeniable tone of dominance.

You approach the massage table, a bit unsure what to expect. Jackie pats her thigh invitingly. "Lay down here with me, let me help loosen you up."

Excellent! Now just relax and let me work my magic on those tight muscles. She starts by gently rubbing your back and shoulders, eventually working her way down to your ass cheeks and thighs. Her hands are strong yet surprisingly gentle as she massages you, occasionally letting a fingertip brush against your perineum or balls.

After several minutes of warming up, Jackie pins your arms above your head with one hand while the other slips between your legs, rubbing circles around your growing erection through your workout shorts. "Mmm, you're getting nice and hard for me already." She leans forward to whisper in your ear. "You ready to feel something even better?"

Don't worry, sweetie. I promise this will feel good. She reaches down with her free hand and unfastens the metallic belt holding up her pants, letting them drop to the floor revealing her thick cock standing at full attention. "Just let me help you out," she says as she positions herself between your legs. "This'll make everything feel so much better."

With one quick thrust, Jackie pushes her massive cock deep into your tight ass. You cry out in surprise and pain as her girth stretches you wider than anything ever before. Jackie groans loudly, taking in a shuddering breath as she bottoms out inside of you.

Her free hand finds its way to your dick through the thin fabric of your shorts, stroking it in time with her hips as she begins to thrust into you harder and faster. "Oh fuck yeah," she pants

You get used to it quickly enough, your body adjusting to the foreign intrusion as she fucks you mercilessly on her makeshift dungeon bed. With each thrust, her cock hits something deep inside of you, sending shockwaves of pleasure through your entire body. Jackie's hands are calloused from hours spent at the gym, and they grip you possessively as she takes what she wants with forceful abandon.

Her breathing becomes ragged as her climax nears, hips bucking wildly as she pounds into you again and again until finally, she shudders violently, thrusting hard one last time before collapsing on top of you, her weight pressing down on your chest as she comes.

She's still inside of you, panting heavily, when she whispers in your ear: "That was just the warm-up."

"Oh, don't worry about that, sweetheart. I have plenty more planned for you tonight," she says, still panting heavily as her cock begins to slide out of your ass. You let out a moan as she pulls free, leaving you feeling empty and aching for more. "Now why don't we move on to the next part of our little workout?" She asks teasingly, glancing over at the massive exercise ball in the corner.

Her hand returns to caress your upper body as she looks down at you expectantly, her gaze hinting that there will be plenty more where that came from if you're a good boy and do exactly what she tells you.
